Easy Creamy Spinach Mushroom Lasagna

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

2 tablespoon olive oil

3 cups fresh spinach, roughly chopped

2 cups mushrooms, sliced

3 garlic cloves, minced

Salt and pepper to taste

3 tablespoon butter

3 tablespoon all-purpose flour

3 cups warm milk

½ teaspoon ground nutmeg

9 lasagna noodles

2 cups shredded mozzarella cheese

½ cup grated Parmesan cheese

1 cup ricotta cheese

Directions

I preheat the oven to 375°F (190°C).

I heat the olive oil in a skillet over medium heat, add the mushrooms, and cook them for about 5 minutes until softened.

I stir in the spinach and garlic, cooking until the spinach wilts. I season everything with salt and pepper, then set the mixture aside.

In a saucepan, I melt the butter over medium heat. I stir in the flour and cook it for 1–2 minutes.

I slowly whisk in the warm milk until the sauce becomes smooth and thick. I season it with nutmeg, salt, and pepper.

I spread a thin layer of béchamel into a 9×13-inch baking dish. I add three lasagna noodles, one-third of the spinach and mushroom mixture, dollops of ricotta, mozzarella, and another layer of béchamel.

I repeat the layers two more times.

I finish with the remaining béchamel, mozzarella, and Parmesan cheese.

I cover the dish with foil and bake it for 25 minutes. Then I remove the foil and continue baking for another 15 minutes until the top is golden and bubbly.

I let the lasagna rest for 10 minutes before slicing and serving.

Variations

I sometimes add sautéed onions to the vegetable filling for extra sweetness and flavor. When I want more protein, I mix cooked lentils into the spinach and mushroom mixture. I also enjoy adding chopped zucchini or roasted bell peppers for more vegetables. For a richer flavor, I substitute part of the mozzarella with fontina or provolone cheese. If I prefer a little heat, I sprinkle in crushed red pepper flakes between the layers.

Storage/Reheating

I store leftover lasagna in an airtight container in the refrigerator for up to 4 days. For longer storage, I wrap individual portions tightly and freeze them for up to 3 months. When reheating, I warm slices in a 350°F (175°C) oven until heated through, or I microwave individual portions in short intervals until hot. If the lasagna seems slightly dry, I add a small splash of milk before reheating to help maintain its creamy texture.

FAQs

Can I use frozen spinach instead of fresh?

I can easily substitute frozen spinach. I make sure to thaw it completely and squeeze out as much excess moisture as possible before using it.

Do I need to cook the lasagna noodles first?

I cook traditional lasagna noodles according to the package instructions unless I’m using oven-ready noodles, which can be layered directly into the dish.

Can I prepare this lasagna ahead of time?

Yes. I assemble the lasagna up to one day in advance, cover it tightly, and refrigerate it until I’m ready to bake.

What mushrooms work best?

I usually use white button or cremini mushrooms because they provide a mild, earthy flavor that pairs perfectly with the creamy sauce.

Can I freeze the entire lasagna?

Yes. I wrap the baked or unbaked lasagna tightly with plastic wrap and foil before freezing. I thaw it overnight in the refrigerator before baking or reheating for the best results.

Conclusion

I love serving this Easy Creamy Spinach Mushroom Lasagna because it delivers rich, comforting flavors in every bite. The creamy béchamel, cheesy layers, and hearty vegetables come together to create a satisfying meal that’s perfect for family dinners, gatherings, or meal prep. It’s a classic vegetarian comfort food that I always enjoy making again and again.
